John’s Lifetime of Learning

Clip: Season 3 Episode 3 | 9m 48s

John learns about medicinal plants during summers with his grandfather in the woods of New York State. He began college in biochemistry, later switching to Marine biology, and getting his degree in 1969. The Red Desert, with its marine fossils, proved an ideal home. Doing cooperative studies with the US forest service and game and fish department's led to numerable opportunities.
